Ireland also has a lower teen pregnancy rate than the European average (4.7% in comparison to the EU average of 5.4%), a rate that last year fell to its lowest in 50 years, according to the CSO.
Ireland does, however, have a higher than average proportion of women in their 40s giving birth for the first time (3.4% versus the EU average of 2.8%) — an age group that has a higher rate of complications in pregnancy and childbirth.
